VIDEO: Katt Williams Has Onstage Meltdown

On Friday, during a concert at the Oracle Arena, Williams began removing his shirt and sweating profusely while spewing out a rambling set of monologues. All within the span of ten minutes, he began verbally attacking a heckler and threatened to fight the individual backstage.

He was later escorted off of the stage by his security, leaving fans upset and demanding a refund.
